Wondering what your first-ever tweet was? For its eighth birthday tomorrow, Twitter launched a tool that helps users travel back in time and find their very first tweets.

The social networking service allows users to type in their username using the #FirstTweet tool, which instantly pulls up the content.

“In 2006, people began to say a little something on Twitter through 140-character bursts of plain text,” Twitter wrote in a blog post. “Eight years later, our users have transformed Twitter into a place where you can discover new ideas, make real human connections and express yourself freely.”

Here’s a look at a few notable Twitterers’ first tweets.
